The SDS plus-3 Drill Bit offers durability when drilling in concrete. To prevent heat development, the 4-flute dura design provides effective dust removal for increased endurance. It is made of high-alloy steel, which is produced with an optimised hardening technology to withstand wear. For additional resistance, indented cutting edges are made from an ideal Bosch-controlled carbide blend. The bit is intended for work on concrete and masonry and is to be used with rotary hammers with SDS plus holders. \n\nAs proof of quality, the drill bit bears the test mark of the PGM Masonry Drill Bit Association Board, guaranteeing compliance with tight tolerances, exact drilling and the firm hold of fixings.\n\n- 4-flute dura design provides effective dust removal for increased endurance\n- High-alloy steel produced with optimised hardening technology to withstand wear\n- Indented cutting edges made from a Bosch-controlled carbide blend provide additional resistance
